TB 40" M W3D, A classic! Wildly popular for many years, and still
easily found on favorites lists and in commerce. From Cooley's Gardens
catalog for 1938: "A new iris so far in advance of others of similar
color combination that they are simply not in the race. With clean
white standards and bright purple falls, it might have been called
'Elk's Temple,' so well does it call to mind the colors of that well
known fraternal organization. The flowers are large and are borne on
well branched stalks reaching almost forty inches in height."

(Dorothy Dietz X Cantabile), HM 1937, AM 1938, Dykes Medal 1940.

Note: The variety Bright Hour is often passed around as Wabash. The
true Wabash has purple based foliage (PBF), Bright Hour does not.
